A Multidisciplinary Approach to Unlocking Television Broadcast Archives

چکیده
Audiovisual material is a vital component of the world’s heritage but it remains difficult to access. With the Netherlands Institute for Sound and Vision as one of its partners, the MuNCH project aims to investigate new methods for improving access to a wide range of audiovisual documents. MuNCH brings together three research fields: multimedia analysis, language technology and semantic technologies. Within the MuNCH project we have investigated several combinations of these fields. We have compared text matching, ontology querying, and semantic visual querying as methods to translate a multimedia query to the vocabulary of the retrieval system. In addition, we have investigated how users make such a translation, and have used this as a benchmark to create automatic methods. We have used multimedia technology to automatically detect objects and scenes as they occur in video, and made use of language technology to exploit automatic transcriptions of speech. We have enriched the Sound and Vision thesaurus that is used to annotate the TV programmes in order to provide a user with a wider range of search
